Overview
DBK208 Carrier Board for Opto-22 Compatible Solid-State-Relays
DaqBoard/2000 Series and cPCI DaqBoard/2000c Series boards communicate [external from the host PC]
through a 100-pin P4 connector. The P1, P2, and P3 connectors discussed in association with these boards
are subset connectors of the 100-pin P4 connector. Chapter System Connections and Pinouts, includes
pinouts for P1, P2, P3, and P4.
The information included in this section, when combined with that found in the related DBK option cards
and modules subsections should enable you to set up your desired configuration.
DBK208 is a two-bank carrier board for optically-isolated Solid-State-Relay (SSR) modules. Each bank
supports up to eight digital I/O modules. The banks can be independently set as “input” or “output” via
jumpers (JP0 for Bank 0, and JP1 for Bank 1). The I/O modules are industry standard Opto-22 compatible,
5-volt logic level modules.
